Here's the 4th video in the video series I'm creating and this one is the longest at 11 minutes. Cosine, tangent, and sine are all incorporated as I build upon the concepts introduced in the first 3 videos. The best way to view it is using the expanded view directly on Youtube and changing the setting to 1080p: https://www.youtube.com/watch?v=xQlnJvasigM.

I really like the video format because it's completely scalable and flexible. Beginners can watch them in order, or more intermediate/advanced measurers can pick and choose which ones to focus on. As I start to get a bigger library of these I'm hoping it can also help bridge the gap when we're trying to help someone through long distance learning.

Hopefully, your excellent videos will enhance long distance learning and will work in the AF National Cadre. I have come to believe that serious tree measuring can use all the teaching tools we can develop.
